eSIM Travel Tips for Dominica

Sort your data before your flight from Dublin
Buy your HelloRoam eSIM for Dominica at home, activate it over Wi-Fi, and enable data when you land in Roseau. You skip the airport telecom queues entirely and step off the plane already connected.
Keep your Irish number active
On a dual SIM phone, keep your Eir, Three IE, or Vodafone IE SIM for calls and texts while using HelloRoam for data in Dominica. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks
Download Google Maps or Maps.me for Roseau offline before you leave Ireland. Offline navigation saves data and works even in indoor areas with weaker signal. Dominica cities are generally well covered but rural areas can be patchy.
Travel insurance and emergency numbers
Bring your EHIC or travel insurance details. The emergency number in most countries is 112 or local equivalents. Your HelloRoam eSIM keeps emergency apps, insurance portals, and the Irish embassy contact details accessible throughout your Dominica trip.
Currency and card acceptance
Notify your Irish bank before travelling to Dominica. Card acceptance is generally good in Roseau but carry some local currency for smaller vendors and public transport. Currency conversion apps work well on a HelloRoam data connection.
